Is our project profitable? To figure this out, you can calculate one simple metric titled ROI; the formula is:

roi

  • Earnings, the sum of the column 'money_spent'.
  • Losses, the sum of the column 'cost'.
Task

Swipe to start coding

  1. Calculate the sum of the column df['cost'], and assign it to the variable cost_sum.
  2. Calculate the sum of the column df['money_spent'], and assign it to the variable spent_sum.
  3. Calculate ROI:
  • Subtract cost_sum from the spent_sum.
  • Divide the subtraction by the cost_sum.
  1. Output the ROI.

The result was already multiplied by 100 to get it in percentage.
